Was Voynichese meant to be pronounced?

One thing that stuck out to me in my reading is that in a typical monastic scriptorium, for maximum efficiency, there would be someone standing at a raised lectern reading the original text slowly and loudly, while multiple scribes would copy down what they heard at the same time.

This was for gospel texts, ones that were expected to be sold "for the mass market", mainly students and the like. 
By the 14th century, mass productions of manuscripts had mainly moved away from monastical scriptoriums and into secular copy houses, that hired people to produce texts to be sold at a profit.
Illustrated texts, such as the VM, not so much. I don't think anyone really contends that the VM isn't a personal copy, even if more than one person was involved in writing it. There is no sign that any professional copy scribe was involved - no lines, no copy checking, no scriptorium notation, nothing that a professional scribe would be expected to include in his work.
